You can use washing soda and a battery charger to remove rust on anything you can submerge in a tank. https://www.garagejournal.com/forum/...emoval.154196/

Hi,
a moderately strong solution (5%-10%) of phosphoric acid. Paint it on, leave for an hour or so to dissolve the rust, and then thoroughly rinse it off.
This is the basis of quite a few of the 'Etching Primer' solutions. Old school but it works.

Hi Jubee - double strength vinegar works a treat (normal vinegar to just takes longer) and is friendly on the skin... If you can put it in something and soak it the rust will be gone overnight. A nylon bristle brush will remove the plaque easily after a soak. Peter

much appreciated.
I still have a few things to do, so will try that as well. Thanks Peter

here is a before and after photo with phosphoric acid i bought from Bunnings. It really turned the rust black and bubbled up into Black goo.

I cleaned it up and looks good now.
